ive had my pitpro 140 for about 4 months now... and i am having troubles with my kickstart.... theres too much compression.... when i kick it, it will shoot back up really quickly.... any advise on how i can fix this problem???

[lil_kiwi_kid]

do u know what the problem is??? coz i have no idea....

Have you got an inner rotor or anything? Kick back is caused by the spark plug sparking at the wrong time sending the piston back before the engine fires. So it's a timing problem..Have you done anything to alter it?

my kickback is really hard and fast all the time?

its because ur kicking it wrong, u have to get it to TDC and then kick it

[MITTZ]

well i get mine to that nice hard spot and it kicks over fine

as has been mentioned time and time again how you kick the bike is vital, remember you got a 4 stroker not a 2 stroker so don't just kick away.
When kicking it around to "TDC" don't kick it fast, just kick it around slowly.

Please correct me if I am wrong but the bike will spark just before TDC (anywhere from 5-15 degree would be my guess) this means if you actually have the bike at TDC then you won't get kickback. Problem is most people think they have TDC when they are still 15-50 degree away because they are coming up on the compression stroke and it gets harder.
If you go past TDC it is easier to kick as the compression stroke is over and as the piston comes back down by itself you simply give it lots more speed.

a clue?
on big bikes you can get a decompression cam but not sure if they are available for these little china's
